Demographic and evolutionary inferences from large, whole-genome datasets. A new data structure for genome-wide datasets has allowed great improvements in the efficiency of genomic data storage and in population genomics simulations, which are crucial to developing and testing mathematical models of population history and species evolution. We will take these advances in new directions, using efficient data structures to dramatically improve inferences about: the demographic histories of populations, rates of genome change, and phylogenetic networks, and we will develop the first inference methods for the multispecies coalescent with recombination. Outcomes will include advances in understanding the evolutionary histories of humans and other species, including pathogens of importance for global health.Read moreRead less

Beyond pineal melatonin: sensing the seasons without the eye. The project will identify the causal connection between seasonal breeding in animals and a recently recognised brain biochemical pathway by applying experimental treatments mimicking seasonal environmental changes in a mutant and wild-type nematode worm model. Through experimentation we will identify useful biological targets that might be manipulated to enhance control of seasonal breeding in managed animals. With better control of r ....Beyond pineal melatonin: sensing the seasons without the eye. The project will identify the causal connection between seasonal breeding in animals and a recently recognised brain biochemical pathway by applying experimental treatments mimicking seasonal environmental changes in a mutant and wild-type nematode worm model. Through experimentation we will identify useful biological targets that might be manipulated to enhance control of seasonal breeding in managed animals. With better control of reproductive output in animals, farmers and managers can increase and/or decrease reproductive output as needed in managed species including livestock and vertebrate pests. This will enhance the use of precious land resources and minimize ecological damage from overbreeding.Read moreRead less
Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this ....Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less
Targeting the genome and epigenome of the exercising skeletal muscle. This project aims is to discover epigenetic and genetic biomarkers that predict fitness changes, following exercise intervention. Individuals are remarkably variable in their responses to exercise interventions, and a large portion of these responses is attributed to genetics, and epigenetics (the effect of the environment on the expression of genes). Using controlled exercise training as a model, this project expects to disco ....Targeting the genome and epigenome of the exercising skeletal muscle. This project aims is to discover epigenetic and genetic biomarkers that predict fitness changes, following exercise intervention. Individuals are remarkably variable in their responses to exercise interventions, and a large portion of these responses is attributed to genetics, and epigenetics (the effect of the environment on the expression of genes). Using controlled exercise training as a model, this project expects to discover epigenetic and genomic markers in skeletal muscle predictive of exercise adaptations. This will contribute to the development and future delivery of targeted and personalised exercise programs for the general population. This has important implications for improving health in the Australian population.Read moreRead less

Epigenetic inheritance: how does it work? This project aims to determine the mechanisms responsible for the inheritance of acquired traits. Sometimes the environment can have effects on the phenotype of not only the exposed individual, but also their children and grandchildren. While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens. This project will use the model organism Caenorhabditis elegans, innovative new techni ....Epigenetic inheritance: how does it work? This project aims to determine the mechanisms responsible for the inheritance of acquired traits. Sometimes the environment can have effects on the phenotype of not only the exposed individual, but also their children and grandchildren. While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens. This project will use the model organism Caenorhabditis elegans, innovative new techniques for the discovery of low abundance RNA molecules, and fluorescence microscopy to analyse structures within the cell nucleus to determine what the molecular mechanism is by which this "transgenerational epigenetic inheritance" occurs. This will have an impact on evolutionary theory, as well as long-term consequences for the understanding of human health and disease, and the impact of a changing climate on agriculture.Read moreRead less
